Braille Pattern Dots 15678

Only within a specific code. Braille is raised-dot writing read by touch. ⣱ sets dots 1, 5, 6, 7, and 8. Unicode stores that shape; a language-specific Braille code supplies its reading. In dot art, proportional fonts may disrupt a picture’s alignment.

In 1821, a Paris school tested Charles Barbier’s twelve-dot “night writing” for silent battlefield messages. Louis Braille reshaped it into six dots readable under one fingertip; he refined the system by 1824 and described it in a book in 1829. Later codes covered languages, music, mathematics, and computer notation.
